[lxc-users] LXC bind Mount Permissioning

[Nicholas J Ingrassellino]

Howdy!

I am experimenting with ZFS and LXC.

As a test on my host I have two ZFS filesystems: //tank/lxc/ for 
containers and //tank/lxc_postgresql/ for bind mounting in a container. 
I have the container fstab working (//tank/lxc_postgresql 
var/lib/postgresql none bind/) where //tank/lxc_postgresql/ on my host 
is equivalent to //var/lib/postgresql// within the container.

The problem comes when I try to install PostgreSQL. It complains that, 
during install, it can not change the permissions on 
//var/lib/postgresql//. I have tried changing the permissions from the 
host (to the same permissions the rest of the folders in //var/lib// 
have) and from the container. I have tried bind mounting at 
//media/postgresql// and creating a symlink to //var/lib/postgresql// 
(not so much because I do not understand why it failed but because I was 
running out of ideas). I am not sure how to get this working...

I ultimately want to do this with a number of containers (some should 
have dedup, some should have a different block sizes, ect) but can not 
even get it working with a single container. Any ideas would be appreciated.

Thanks in advance!
